Isoleucine (Isoleucine)

An amino acid used in cosmetic formulations as a skin and hair conditioning ingredient, valued for its contribution to hydration, softness and a more revitalized appearance. By complementing the amino acid profile of the formula, it helps improve the feel of dry, dehydrated, tired or tone-lacking skin, supporting a smoother, more supple and well cared-for surface. In creams, serums, lotions, cleansers and hair care products, it enhances the conditioning character of the formulation, improves the pleasant touch of skin and hair, and contributes to a fresher, more balanced and healthier-looking cosmetic finish.
